New Specialized Design Tools Automate Early Phases of Product
Development and Multi-Stage Manufacturing Processes for Efficient
Creation of Large or Complex Composite Parts

WALTHAM, Mass.—(BUSINESS WIRE)—March 20, 2006—
VISTAGY, Inc., the developer of engineering software that provides
specialized design functionality to commercial CAD/PDM/PLM systems,
today announced the release of FiberSIM(R) 5.1, the latest version of
its design environment for composite products. FiberSIM 5.1 provides
new specialized tools that enable engineers working in commercial CAD
systems to automate design processes early in product development.
This results in more efficient and accurate manufacture of complex or
large composite parts, including products produced in multiple stages.

"With FiberSIM 5.1, we've reinforced our commitment to helping
engineers capitalize on the vast potential of composite parts and
development processes so they can create cutting-edge, innovative
products," said Bob Flory, vice president of product development at
VISTAGY, Inc. "By automating many of the most repetitive or complex
composites design tasks early in development, FiberSIM 5.1 enables
engineers to select the optimum product design choices and
manufacturing methods to reduce cycle time and costs. As a result, our
customers will realize a significant competitive advantage with
FiberSIM 5.1."

FiberSIM 5.1 introduces a number of new features that enhance the
latest composites design and manufacturing processes. The software
provides three primary advantages:

-- Automation earlier in the product development process.
Engineers who produce large or complex composite parts utilize
FiberSIM to help them design and validate laminates, zones,
layers and ply sequences. The software provides new
capabilities to automate design methods earlier in product
development for more efficient manufacture of composite parts.
For example, the new Merge Model capability enables engineers
to quickly and automatically divide an electronically
generated model, such as a representation of an aircraft
fuselage, into several separate models and combine them again
at a later time. This capability allows a number of engineers
to simultaneously work on the parts of a large composite
product to significantly decrease development time. The
Symmetric Laminate Utility generates a model, such as an
aircraft's composite left wing section, and then applies all
the data to automatically create a corresponding structure for
the opposite, righthand side, saving hours of manual design
time.

-- Capabilities specifically designed to optimize various
composites product development processes. Composite designs
will not be economically feasible unless they are tailored to
the specific manufacturing processes being used to produce
them. The new Automated Deposition Design(TM) (ADD) option
automates the creation of composite product geometry that is
specific to manufacturing processes such as tape-laying or
fiber placement, saving weeks of manual work for large
structures. The new Extended Ramp Object, for example, extends
boundaries of material and defines a natural drop-off to make
it easier for a fiber placement machine to 'ramp up' onto a
tool and do its job properly. FiberSIM 5.1 provides unique
tools for ply lay-up, material overlay, tape-laying and
splicing that optimize composite designs for quicker
downstream manufacturing. There are also new documentation
enhancements, such as automatic generation of 2D plybooks that
list the sequence of laminate plies, eliminating drawings and
manual note-taking methods used prior to FiberSIM.

-- The creation of a complete product definition that can be
easily leveraged downstream. With the breadth of new
capabilities in FiberSIM 5.1 and support of open standards,
engineers can create a complete composite design definition
with all associated citations and data necessary to drive
downstream processes. Using the power of Extensible Markup
Language (XML), the complete data set can be easily shared
across the enterprise. As a result, engineers understand the
history and context of design details, which helps minimize
potential errors downstream, achieve desired part quality, and
meet specifications in a fraction of the time of traditional
processes.

VISTAGY, Inc. develops engineering software that provides
specialized functionality to significantly improve the value of
commercial 3D CAD systems. VISTAGY's specialized engineering
environments enable engineers to capture and communicate complete
digital product definitions within CAD, thereby increasing
productivity, improving the communication of product information
throughout the product lifecycle, and allowing better-informed
decision-making early in design. VISTAGY software is used throughout
the world in the aerospace, automotive, marine, medical, sporting
goods, and transportation interiors industries. The company also
offers training and consulting services. For more information, contact
